2 Claims. (Cl. Z39- 281) This invention concerns new and useful improvements in an adjustable sprinkler for lawns.

The invention has for an object, the construction of a sprinkler which is characterized by an outer tube extending from the top of a hollow cylindrical body connected with a supply of water, a rst spray-directing nut mounted upon said outer tube for controlling spraying of water from an area around the tube and within the hollow body, and an inner tube extending coaxially through said outer tube and provided with another spraydirecting nut for controlling the spraying of water which passes between said outer and inner tube, said inner tube having a central axial bore and provided with a perforated cap for emitting water in a tine axial stream from the inner tube.

A further object of the invention resides in a novel way for supporting the several tubes with respect to each other, in the hollow body.

A still further object is the provision of a novel supi port for the sprinkler body whereby the sprinkler is enabled to be wheeled about on a lawn, while the body is maintained in an erect position.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in whichI the various novel features of the invention are more particularly set forth.

In-the accompanying drawings forming a materialfpart of this disclosure:

Fig. 6 is an enlarged elevational view partly in section of the upper end of the outer tube and spray-directing nut.

Fig. 7 is a bottom horizontal sectional view taken on lines 7-7 of Fig. 6.

The adjustable sprinkler for lawns according to the invention as shown in Fig. l, includes a main water supply pipe 10, provided with an elbow end 12 having a coupling 14 thereon whereby a mating coupling 15 on the end of hose 16 may be attached to the sprinkler. The hose and coupling are shown schematically by dotted lines in Fig. 5. Pipe 10 is supported in a vertical position by a cylindrical sleeve 18 provided with a thumb screw 20 for adjustably positioning the pipe 10. The sleeve is supported by three legs 22, 24 and 26. Legs 22 and 24 are secured to the sleeve by screws 28. These legs are bent to curve and flare outwardly and downwardly, and terminated in vertically disposed flanges 30. The flanges carry pintles 32 on which are journaled wheels 34 upon which the sprinkler rests. The third leg 26 is secured to sleeve 18 by screws 35 and flares outwardly and downwardly in a plane midway between the angularly disposed vertical planes in which legs 22 and 24 are disposed. The free end 26a of leg 26 is coplanar with wheels 34 and serves as a friction rest element to prevent wheeling movement of the sprinkler when it is in a free standing position. This free curved end of the leg 26 will engage in the grass or soft turf in'alawn to keep the sprinkler in a stationary position.

Axially aligned with pipe 10 and telescopically disposed therein is a rigid plastic tube or pipe 38. The upper end of pipe 38 is threaded in the lower tapered end of a fitting 40. This fitting is secured in the lower end of a cylindrical sprinkler body 42. A similar tapered fitting 44 is secured in the upper end of body 42. The open upper end of fitting 44 serves as a nozzle for ejection of water from the body. Centrally disposed in body 42 is a first outer tube 46. This tube'has lower and upper sections 46a and 46b respectively interfitted with each other. Section 46 is provided with aplurality of apertures 48 at intermediate points therein. A cylindrical web 50 is secured on the lower end of section 46a. This web, as best shown in Figs.- 2 and 3, has a plurality of spaced holes or passages 49 therein. Section 46a has a central bore 52. Section 461 has two sets of apertures 53 and 54 spaced near opposite ends thereof. Section 46b has a central bore 56 and is externally threaded at its upper end 58. Threaded on end 58 is a water stream directing nut 60. This nut has a knurled outer rim 61 to facilitate turning and adjusting the nut to regulate the volume of water emitted as spray S1 from the nozzle end of fitting 44. The underside of the nut is tapered inwardly at 60a so that the water is cast in a uniform 360 spray S1 from the sprinkler body.

An inner tube 64 is concentrically disposed in the upper half of tube section 46h. The tube 64 has a central bore 65 and is threaded on its upper end at 66. A perforated cap 68 is threaded on the end of tube 64. Thelower end of tube 64 is provided witha ange or web 63 by which the tube is secured to the wall of bore 56 in tube section 46". Threaded on tube 64 is a second water stream directing nut 69 having a lower curved and tapered side 69a, so that the stream of water Sg which is emitted from the passage 67 dened between ltube 64 and tube section 46b is cast as a uniform 360 vspray around the sprinkler. A third spray S3 is cast' centrally upward through the opening 68.a in cap `68.

In'order to mount 'pipe 38 teleSCOpically in pipe 10 there is provided a' generally cylindrical clamp sleeve 70 having a bore with an internally threaded portion 72 adapted to be threaded on the upper externally threaded portion 73 of pipe 10. A shoulder 74 is formed near the other end of the bore in sleeve 70. Against this shoulder. seats one or more resilient rubber washers 76. When the sleeve 70 is fully threaded on pipe 10 these washers are compressed and caused to grip the exterior of pipe 38 so that the pipe 38 is held in a selected elevational position.

In Figs. 6 and 7 is shown a preferred arrangement for the upper end of tube section 46h whereby the nut 60 is adjustably held in a ixed position. An H-shaped cut 80 is formed in the threaded portion 58 of tube section 46h. Two lips 75 defined by the H-shaped cut are bent outwardly as clearly shown in Fig. 7. The underside of nut 60 which is threaded on portion 58 has a countersunk bore portion 60b which ares outwardly to a diameter slightly larger than the maximum radial projection of lips 75. Thus, when the nut is threaded down on tube section 46h, the lips 75 are forced inwardly and the nut is turned against gradually increasing tension in the llexible lips. It is preferred that the tube section be formed of a metal having some resiliency so that lips 75 will serve as friction inducing spring ele- 3 ments, to inhibit free rotation of nut 60. If desired, the threaded end 66' of tube 64 can be similarly provided with one or more lips?` for retaining nut 69 in a selected position on tube 64.

In operation of the device, hose 16 is attached before or after the sprinkler is tilted up on wheels 34V and wheeled to a desired location to be watered. Then the sprinkler is anchored by pressingl the leg 26 down into the ground. Nuts 60 and 69 and cap 68 may be adjustably threaded on their supports vto regulate the volume of the spray to pass each of these elements. The water passing out as spray S1 will normally pass apertures 49 inV web 50, then through the space between bore 43 in body 42 and the tube 46; The water passing out as spray SZ will enter tube section 4Gb through apertures 54. The water passing out as spray S3 will pass up bore 65 from bores 52. and. 56. Some water .may enter bore 56 directly throughl apertures53' and some; water may enter bore 56 through 'apertures 48.

The sprinkler body, tubes and nuts should preferably be made of bronze, brass or other non-corrosive metal. The body 42 and sleeve 70 may 'be made of aluminum.

While I have illustrated and described the preferred embodiment of my invention, it is to beunderstood that I do not limit myself to vthe precise construction herein disclosed and that various changes and modiications may be made within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
